An insightful Ars Technica editorial examines this question in depth, concluding that Apple's walled garden approach to iOS is fundamentally flawed and thus Microsoft should reconsider their plans to apply the same model to WinRT. The authors are careful to present a nuanced analysis that adequately weighs the competing interests of security, convenience, and user freedom, ultimately concluding that Mac OS X and Android offer better models because while their walled gardens are on by default, they offer supported mechanisms to opt-out if desired, thereby offering users the same security and convenience benefits without sacrificing user freedom in the process."
